Patent EP-0392992-A2 (EP)
Inventor: JONES MICHAEL E
IPC: F16K1/10
Filed: 1990-04-06
Abstract: A sealed valve intended for use in ultrahigh purity applications uses a metal-to-metal seal in a crucial, but unaccessible, portion of the valve. The metal-to-metal seal avoids the use of a weld which because of the location could not be adequately cleaned, and avoids the use of an O-ring seal. The O-ring seal typically would have a leak rate on the order of 10⁻⁷ standard cubic centimeters per second of helium, but the metal-to-metal seal provides a leakage rate of less than 10⁻¹³ sccm/s. In the preferred embodiment, the seal is formed by forcing a conical part into the opening of a bore. The force used is small enough to avoid permanent deformation of the sealing parts, and thus the seal can be opened and closed any number of times without degradation.

Abstract: 2.1 For measuring the resistance of protective conductors and potential compensating lines, a direct voltage source is required for generating the required measuring current. The components of the circuit arrangement are to be protected against hazardous external voltages which can occur with operating errors without parts of the protective circuit such as, for example, fuses, having to be exchanged in the case of a fault. 2.2 On one side of the object to be measured (Rx), a blocking diode (V4) is inserted and on the other side a controlled semiconductor switch (V8) is inserted into the circuit. A control circuit (L) controlling the semiconductor switch (V8) is designed in such a manner that it blocks the circuit via the semiconductor switch (V8) as soon as the aggregate voltage formed by the direct voltage source (U0) and at the external voltage exceeds the threshold voltage of a threshold element (V5) belonging to the control circuit (L). 2.3 The test instrument is to be used for measuring a resistance, particularly the resistance of protective conductors and potential compensating lines. <IMAGE>

Abstract: The invention relates to a device for deflecting a light beam by diffraction on an optical grating. Such deflection of a light beam is necessary in optical measuring instruments, for example gas or liquid analysers. These require, in particular, a variable deflection, e.g. a circular deflection; i.e. the deflected beam describes a circular path. The latter is achieved in known devices with the aid of mechanically moved, optical arrangements, but these have disadvantages in respect of wear and cost. A device according to the invention results in a circular deflection of a light beam by diffraction of the light beam on a rotating optical grating. The optical grating is realised here by the density differences in a preferably liquid medium which is situated in a cylindrical vessel. The density differences are caused by ultrasonic vibrations and generated with the aid of ultrasonic transmitters which are mounted on the circumferential surface of the cylindrical vessel. The rotating optical grating is produced by sequential triggering of the ultrasonic transmitters. <IMAGE>

Abstract: Object of the present invention is to provide a controller for distribution apparatus which prevents extension of power failure. When a short circuit accident, for example, occurs in one control circuit (100A) for distribution apparatus, a breaker (15) for distribution opens, an auxiliary coil (18A) becomes unexcited, and power failure is caused, but an auxiliary contact point (18B) of the unexcited auxiliary coil (18A) closes in another control circuit (100B) for distribution apparatus so as to excite a closing coil (10), and consequently, the other control circuit (100B) starts its operation immediately. Accordingly, extension of the power failure can be prevented and reliability of power supply can be safely maintained.

Abstract: A quantum wave guiding electronic switch includes a substrate (1) which carries electron waveguides (6, 7, 8) disposed in a forklike configuration. Each of these electron waveguides is connected to a respective electron reservoir (3, 4, 5). Electrons are driven through the waveguides by voltage sources (15). Electrodes (10, 11) on the substrate (1) generate an electric field (E) which passes through the outgoing electron waveguides (7, 8) of the switch, and creates a potential difference therebetween. In one case, in which the electrons are transported ballistically, in the absence of electron scattering, this potential difference creates a phase mismatch between the outputs (7, 8). An incident electron wave function (Ψ) having even parity is herewith switched to a quasi even electron wave function in the output (7, 8) that has the lowest energetic potential. When transportation is not ballistic and the electrons scattered to some extent, switching is effected by relaxation of incoming electrons to lower energy levels. The electrons will have a higher probability to be conducted through the output (7, 8) that has the lowest potential. The two switching cases may occur simultaneously in part. The switch is digital and requires very little control energy. Electrons within a broad energy range are switched and the switch has small or no losses.

Abstract: A method for forming a pattern where the processing is simplified by using a silylated photoresist film, having retained the resolution increasing effect according to a multi-layer photoresist film process is disclosed, wherein a first photoresist layer (21) is formed on substrate (20) and part of the surface of the substrate is silylated, to thereby form a silylation layer (23). Then, a second photoresist layer (24) is formed on silylation layer (23), which then is exposed through the photo mask (25) having a predetermined pattern. Then, a second photoresist pattern (24a) is formed after development. Then, a silylation layer pattern (23a) is formed by etching-back the silylation layer (23) using the second photoresist pattern as (24a) an etching mask. Then, the silylation pattern (23a) is oxidized. and the first photoresist layer (21) is etched using the oxidized silylation pattern, thereby forming a first photoresist pattern (21a). A resolution increasing effect can be maintained only through the two layer photoresist film structure without the intermediate oxide film, while the process is simplified and the undesired polymer is less generated.

The extreme values (54-66) of the voltage (U) are determined, and the occurrence of the extreme values (54-66) in relation to a clock time (T) defined by means of the two-frequency code is evaluated for obtaining data. Proceeding from an extreme value (58) used for obtaining data, the time intervals (T1-T4) of successive extreme values (60-66) are measured and added. The extreme value (66) at which the sum (S) corresponds approximately to the clock time (T) is evaluated for obtaining data. <IMAGE>
